摘要

The active center concentration Cp

the rate constant kp

and the activation energy of chain propagation Ep in the polymerization of propylene with complex-type TiCl3-(C2H5)2AlCl catalyst system were studied. The Mn was corrected by Mw/Mn value determined by GPC. The values thus obtained for Cp

and Ep at 50℃ were 3.01 mol/mol Ti

6.27 1/mol·sec

and 5.10 Kcal/mol respectively. The kinetic parameters were compared with those obtained from conventional TiCl3·AlCl2 catalyst

showing that the higher activity of the complex-type catalyst over the conventional catalyst is not only due to the higher Cp of the former

but to a greater extent due to the increase of the kp value.
